130 NORTH AMERICAN 



longer tlian wide, shining, moderately coarsely very evenly and rather 

 densely punctate ; punctures round, impressed, generally distant by twice 

 their widths. Abdomen at base just visibly narrower than the contiguous 

 elytra ; sides parallel and very feebly arcuate on the first four segments ; 

 border nearly equal throughout the same segments, very strong, moderately 

 deep ; surface feebly convex, finely very strongly evenly and rather sparsely 

 punctato-asperate and transversely finely and strongly strigate, shining ; 

 setae at the sides and tip very long, strong and bristling. Legs long and 

 slender ; femora very slender, pale flavate, remainder pale rufo-testaceous, 

 first joint of the posterior tarsi much shorter than the next two together, first 

 four decreasing uniformly in length. Body not paler beneath. Prosternum 

 obtusely angulate behind, angle not at all rounded and very strongly 

 elevated, elevated portion narrowly and feebly carinate. 



Male. — Unknown. 



Female. — Second and third ventral segments each with a very short trans- 

 verse posteriorly arcuate eroded fold in the middle of the disk, about one- 

 sixth as long as the width of the segments, and bearing a very dense line 

 of erect stiff setae ; sixth segment very broadly rounded belaud, transverse 

 in the middle. 



Length 8.0 mm. 



Near Camden, New Jersey, 1. 



Under the supposition that the narrowing of the head behind the 

 eyes is not a constant character, which however I have no reason to 

 suspect, the above species would fall naturally immediately after 

 despecfiim in the table referred to above ; if, however, we consider 

 this as a rigid and constant character, it can find no |)lace under any 

 of till' subdivisions proposed there, as, with crlhratttm and serpentinum 

 it appears to possess very few cliaracters in common, except the one 

 indicated. 



The type specimen was taken on the sandy shores of the Delaware 

 River about six miles from Philadelphia. 



C. parallc'llllll u. sp. — Form slender, depressed ; sides parallel. Color 

 throughout i)ale reddish-brown, iu)t paler beneath ; femora much paler, 

 llavate ; antennae testaceous, basal joint slightly more flavate and the tip 

 more fulvous and paler from an excessively fine short and dense pubescence; 

 head and prothorax less opaque and more purely rufous than the remaiiuier ; 

 sparsely and coarsely pubescent, elytra and abdomen more densely and con- 

 spicuously so. Head two-thirds longer than wide; sides parallel behind the 

 eyes and almost straight posteriorly, broadly rounded to the neck whicli is 

 three-fifths as wide as the head ; eyes rather small, very slightly convex ; 

 epistomal regions before them two-thirds as wide as the head, sides parallel 

 and straight, truncate anteriorly, angles rounded ; antennal tuberculations 

 broad and ver^' prominent ; surface between them feebly declivous and 

 slightly more strongly impressed near them, slightly more sparsely and 

 finely i)unctate ; interocular surface and occiput rather coarsely strongly
